My purchase was for Microsoft.
Phone number i used was the "contact us" number for the eStore
https://www5.aeroplan.com/estore/contact.ep
But it's directed to (or it is) the regular Aeroplan number. Agent answered the call "What can I do for your travel plan?"
When I said I wanted to report an eStore missing miles online form error (so it's really a website technical error) she probably started looking at her cheat sheet for estore and consulting with her lead. I didn't ask her to take my missing points claim or give me the points right away. So she was an excellent agent in that regard.
